2019-2024 Ram 1500 5.7L Hemi Bypass Valves

The stock thermostatic valve on our 2019-2024 Ram 1500 5.7L Hemi is a known point of failure that can lead to high transmission temperatures and potential failures if heat gets too high. The stock valve is prone to getting stuck closed, which prevents transmission fluid flow from your transmission to the transmission cooler. This can cause temperatures to steadily rise until your truck is in limp mode, and can possibly cause transmission damage. Tier One's Ram 1500 5.7L Hemi bypass valves and delete plates take your OEM thermostatic valve out of the equation entirely, allowing full-time fluid flow to your Ram's transmission cooler, improving reliability and transmission temperatures.
